And that's because finding donor hearts for children is tough. None the less the Waddleton's remain confident because Kaleb is soaking up prayers--mostly from strangers. It's courtesy of the "Prayer for Kaleb" social media campaign.

"A friend of ours posted a favorite picture of Kaleb on Facebook, and its gone viral," says Kale Waddleton" From ventilators, breathing tubes to smiling. I've never been a praying man, but since he's been here, it's working"

The family says keep the prayers coming.
